Andrena nasonii. In this case a female, one of the least distinguishable species there is, but fortunately very common and so there are small and differences between the species and others that together allows us to recognize it when plowing through thousands of them.

An abundant Andrena, often found in lawns and disturbed field like situations. The males are as generic as they come but have a tiny point coming out of their integument on either side of the underside of their thorax. Thank goodness. Photographer ...

This tiny bee is a specialist on Willow Pollen, and was captured early this spring, unfortunately it is also completely coated in pollen and lint from the collecting process and did not go through our usual wash and blow dry procedure...thus the bad hair, but on the other hand it shows the characteristic light green tinge to the integument and generally captures the

The abdomen of a female Andrena nivalis. In that abdomen is a female stylopid which looks a bit like an odd head sticking out from underneath a tergite...she has been living in said A. nivalis for a long time...feeding on its innards...and, the stylopid has just given birth, (likely killing her in the process) to all her little babies. Nature: So cruel.

Andrena ilicis. A bit of a mystery bee. It seems to be associated with Woodlands, but other than that I don't have much of a feel for the species. This one was collected in Somerset County Maryland.

From malaise traps set in the woodland bottomlands of the Patuxent River comes the uncommonly detected Andrena illicis. Here is a male with its notable orangish legs.

Andrena lupinorum, Pennington County, South Dakota, Badlands National Park

Andrena macra, a southern bee that just barely makes its way to Maryland. Seems to like to aggregate nests in sandy areas and create small colonies, although colonies are probably a poor word choice, perhaps more likely they just like to nest near one another.

A little tiny Andrena bee collected in the sandhills of North Carolina by Heather Campbell. Not much is know about this species, other than it appears to be uncommon and spotty in occurrence and runs from the West to the East coast with a fair amount of variation, which usually indicates that other species may be hidden within this one. So much work to do.

Andrena merriami, female Badlands National Park, South Dakota

A small spring Andrena, the female uses pollen from Zizia plants to provision her nest. This specimen was captured by Nancy Adamson in the mountains of West Virginia.
